Hi, I am using Firefox browser on Windows 11, Dell machine with Cirruslogic sound driver There is sound intrruptions when a new music source has started while a music already playing on another tab. While a radio or youtube music stream playing on a tab (in background) and if other tab starts a new sound like youtube or video an any page when started the music background got interrupted (like a small pause operation). If I do the same with chrome or opera, the music goes on without promblem seamlesly. Also if a music stream continues, opening a new music stream on chrome do es not effects. So, the only proble ise with opening sound from different tabs interrups each other on only Firefox browser PS:I am using the Treestyle tab extension. I do not know there is a relation or not Regards Murat
